Plot Summary
In 1919, Hannah Parmalee (Fay Bainter) becomes the housekeeper for the family of science teacher Paul Ward (Claude Rains). Struggling to invent an iceless icebox, Paul takes Hannah's advice and invites young student Peter Trimble (Jackie Cooper) to help him. They work together and perfect a prototype, but Peter's poor judgment leads to its theft by mechanics who claim it as their own work. Meanwhile, Hannah keeps an eye on the teen boy, who doesn't know he's the child she gave up for adoption.
